wide variety of functional groups. Reported herein is a direct method for the highly regioselective preparation of 5-membered and 7-membered cyclic ketals in respectable to good yields from aryl bromides (1a–k) and electron-rich olefins (2a and b). The reaction is performed with palladium catalysis using ionic liquid as solvent with no need for any halide scavengers, providing an alternative to the
